The amphipod, Ampithoe valida, presumably native to the Atlantic coast of North America, has been recorded from several other parts of the world. Hitherto, the only published records from Europe originate from Portugal. Evidence is presented that this species has been introduced to northern Europe and the Mediterranean Sea as well.
